What do I need to measure nail size?
Use a millimeter ruler or measuring aid suitable for the method shown in the set's sizing guide, plus somewhere to record your measurements. Check the individual set's information for any supplied sizing card or guide.
How do I measure each natural nail?
- Locate the widest part of the natural nail, from one sidewall to the other.
- Follow the measuring method shown for the nail set and record the width in millimeters.
- Repeat for every finger on both hands; do not assume the other hand uses identical sizes.
- Compare the recorded widths with the size information for that exact set.
- Dry-fit each press-on without adhesive and check the sidewall and cuticle fit.
Nail measurement worksheet
Copy this worksheet and enter your own measurements. Keep the style name with the record so you can check the matching size information.
| Finger | Left hand width | Right hand width |
|---|---|---|
| Thumb | ____ mm | ____ mm |
| Index | ____ mm | ____ mm |
| Middle | ____ mm | ____ mm |
| Ring | ____ mm | ____ mm |
| Little finger | ____ mm | ____ mm |
How should the press-on fit before gluing?
Check how the nail covers the natural nail and meets its sides without overlapping skin. Do not force a press-on into place. Width alone does not replace checking the actual fit.
What if I am between sizes?
Follow the sizing directions for the specific set. Compare both available sizes without adhesive. If neither fits comfortably, ask Glaze Beauty for sizing help with the style name and your measurements before choosing a set.
What if the size chart is missing?
Request the size information for the style you want. A general XS–XL label or the numbers from another brand should not replace the chosen set's own measurements. Do not estimate fit from a product photo alone.
Ready for the next step?
Once the fit is clear, follow the press-on nail application guide. If you are still choosing a style, compare nail shapes or return to the complete press-on nails guide.
